Writing S-Functions

Introduction

There are two main strategies to executing Fortran code from Simulink. One is from a level 1 Fortran-MEX (F-MEX) S-function, the other is from a level 2 gateway S-function written in C. Each has its advantages and both can be incorporated into code generated by the Real-Time Workshop.
